What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of units of orange juice at beginning = 30 units
The number of units purchased = 50 units
Total units = 30 + 50 = 80 units
The number of units at the end = 30 units.
The number of units sold.
= Total units - Units at the end
= 80 - 30
= 50 units.
Thus,
The number of units sold is 50 units.

a) How much does he earn if he works 5 hours?
b) How much does he earn if he works 10 hours?
c) He works 37.5 hours per week.
How much does he earn in a week?
Please help!
Answer:
a) £58.5
b) £117
c) £438.75
Step-by-step explanation:
Mr Singh is paid £11.70 per hour after tax is deducted.
This means that for x hours of work, his earning are given by:
[tex]E(x) = 11.7x[/tex]
a) How much does he earn if he works 5 hours?
This is E(5).
[tex]E(5) = 11.7*5 = 58.5[/tex]
b) How much does he earn if he works 10 hours?
This is E(10).
[tex]E(10) = 11.7*10 = 117[/tex]
c) He works 37.5 hours per week. How much does he earn in a week?
This is E(37.5).
[tex]E(37.5) = 11.7*37.5 = 438.75[/tex]

At this weekend's football game, 15 out of the first 50 people entered in the field were not wearing hats.
The number of people attending the game is 250.
What is Probability?
Probability is a measure of the likelihood of an event to occur.
Now,
Probability for not wearing hats;
⇒ 250/ 50 = 5
⇒ 15 x 5 = 75
Hence, 75 people out of 250 will NOT be wearing hats.

Least common denominator of 3/4 and 3/8
Answer:
8
6/8 and 3/8
4 = 2²
8 = 2³
LCM = 2 × 2 × 2
LCM = 8
The Least common denominator of the fraction numbers 3/4 and 3/8 is 9/24
What is least common denominator?The least common denominator (LCD) of 3/4 and 3/8 is the smallest number that both 4 and 8 can divide into evenly.
The prime factorization of 4 is 2 x 2, and the prime factorization of 8 is 2 x 2 x 2.
Next, we list the prime factors of each denominator and identify any factors that are common to both:
4: 2 x 2
8: 2 x 2 x 2
The common factors are 2 x 2, which means that we only need to include one set of these factors in the LCD.
So, the LCD of 3/4 and 3/8 is:
LCD = 2 x 2 x 2 x 3 = 24
For 3/4, we need to multiply both the numerator and denominator by 6 to get:
3/4 = (3 x 6)/(4 x 6) = 18/24
For 3/8, we need to multiply both the numerator and denominator by 3 to get:
3/8 = (3 x 3)/(8 x 3) = 9/24

52 - 2y = -48
2x + 3y = -23
Answer:
y=50 and x=-173/2
Step-by-step explanation:
52-2y=-48
∴-2y=-100
y=50
and 2x+3y=-23
y=50→(1)
2x+3y=-23→(2)
Putting y=50 in equation (2), we get
⇒2x+3y=-23
⇒2x+3(50)=-23
⇒2x+150=-23
⇒2x=-23-150
⇒2x=-173
⇒x=-173/2
∴y=50 and x=-173/2

What is the domain of f for f(x)=x-3/x+2?
Answer:
(-infinity, -2) ∪ (-2, infinity)
Step-by-step explanation:
I will have to assume that you meant
f(x)=(x-3)/(x+2). You must use parentheses to specify the order of operations in this problem.
x can take on any value except -2, at which the function is undefined.
Thus, the domain is (-infinity, -2) ∪ (-2, infinity)
Dennis is selling chocolate bars for a
fundraiser, and if he sells over $175 worth of
candy, he'll win a prize. If chocolates sell for
$2.50 a bar, and Dennis has already sold $40
worth of candy, then how many more bars does
he have to sell in order to win a prize? (Solve for x with inequalities)
Answer:
54 , 2.50x+40=175
Step-by-step explanation:
Answer:
2.5x + 40 > 175 (Dennis has to sell 55 chocolate bars)
Step-by-step explanation:
When you solve the inequality, you get...
2.5x + 40 > 175
Subtract 40 on both sides...
2.5x > 135
Divide 2.5 on both sides...
x > 54
When you substitute 54 for x in the original inequality you get...
175 > 175
Dennis needs to make more than 175 so he needs to sell 55 not 54.
Hope this helps :)
Please hurry; Which function increases the fastest? A. y 5 14x B. y 5 23 · 17x C. y 5 120x D. y 5 2275x^x
a y = 14^x
b y = -3 (17)^x
c y = 120x
d y = -275x
Answer:The given equation is of the form y = mx + b where m is the slope and b is the y-intercept.
Here, m = -14
Two parallel lines have the same slope. So, the slope of the new line will be -14.
To calculate the y-intercept substitute x=4 and y=4 in the equation.
4 = (-14)(4) + b
Solving for b, we get b = 60.
So, the new equation will be y = -14x + 60
